[Ndn-interest] Questions about jNDN

[Thompson, Jeff]

These are not exposed in the API, as the API is abstracted from the encoding details which change frequently.

May I ask why your application needs to know, for example, the MetaInfo encoding length?  Maybe we can find a way to meet your application needs.  (The API provides some mechanism for manipulating TLV encodings.)

Thank you Jeff

But if I want to get the length of Name, MetaInfo or Signature TLVs in Data packet not the size of the entire packet??

Hi Ahmed, See inline.

I have two questions related to jNDN:

  1.  Does the current version support Nack interest i.e. can I send a nack interest whether the requested content does not exist ?

No not yet,

  1.  I want to get the length of each TLV in Data packet, I means the number of bytes that type, length and value occupy. Does it provide a function to get this ?

You can get the size of the entire data packet TLV with:

   data.wireEncode().size()

Thanks,
- Jeff T
